Isekai Adventure in the Dimensional Cube

The Franser household, annex manor.

The explosions, unknown when they ceased.

The alchemical bombs buried around the manor appeared to have all been detonated and no longer caused damage to the annex.

The surrounding walls of the annex had collapsed, allowing black smoke and flames to billow, and the ground and surroundings were riddled with pits, as if bombarded fiercely by artillery.

At first glance, the situation didn't seem good, but a closer inspection would reveal that except for the courtyard being affected, the entire Franser annex manor was almost untouched by any harm, and there were no casualties among the people, everyone having had a narrow escape.

Servants without fighting capabilities had all sought refuge in the basement.

The knights and guards with fighting capabilities remained, but at most were injured, with nothing serious.

In contrast, those slaves who attacked the Franser household annex were already in a state of heavy casualties.

Some of them lay on the ground, some in puddles of blood, some restrained by knights and guards, some tied up with ropes, each looking somewhat pitiful.

That included the sharp-eyed slave, who likewise fell under Ian's sword, his face full of regret.

It proved that these slaves had no chance of defeating a hundred-man knight troop led by a real swordsman.

The knight troop of the Franser household was known for its strength that even Reiger was astounded by, with most possessing Lv.3—Lv.4 strength; how could a group of people who had fallen into slavery possibly threaten knights who trained every day and were battle-hardened?

The sharp-eyed slave did have some strength, estimated to be comparable to Lv.4, but he unfortunately faced off against a real swordsman equivalent to Lv.5, so the outcome is predictable.

If there were real swordsmen among these slaves, then the Basoro family would surely have taken them in themselves, why would they send them out as sacrificial pawns?

Real swordsmen becoming slaves are very rare, because there aren't many magicians who could forcibly apply slave contracts on swordsmen of this level; without tactical level magic, no magician could enslave a real swordsman.

Real swordsmen who became slaves were the most precious commodities, even if they appeared in the royal market, they would be auctioned as the final item at an auction; how could the Basoro family casually buy them in bulk in the slave district?

Therefore, these slaves who attacked the Franser household, though they had fighting capabilities, ultimately couldn't match the knights of regular knight troops cultivated under a great noble, or else everyone would just buy slaves instead.

This batch of slaves' only highlight was the sharp-eyed swordsman; the rest weren't worth mentioning.

Perhaps it was for this reason that Ian did not kill the slave with a heavy hand, sparing his life.

And when Ian was preparing to have all the slaves escorted down, Ai En, who was responsible for dispersing the personnel and protecting the servants inside the manor, suddenly appeared with an order.

"All to stay in the basement on standby?"

Ian was taken aback.

But immediately after, the whisper Ai En made in his ear had Ian showing an expression of realization, and with a troupe of knights and slaves, they all entered into the basement.

In doing so they missed seeing a person who had climbed up onto the rooftop of the annex manor.

It was Reiger.

"Everyone went to take shelter, huh?"

Reiger looked down on the entire estate from above, and after confirming there was no one else in sight, he finally lifted his head to look at the Tactical Barrier overhead.

"The Basoro family, huh?" Reiger narrowed his eyes, suddenly smiled, and said, "Since you've used me, I shall personally collect this bit of interest."

Reiger was also quite vengeful.

In his previous life, so many unpleasant things had happened, and although he had become numb to them, he always remembered, took them as warnings, and swore not to make the same mistakes in this life, even if it cost him his life.

Attacked by the people of the Freyja Clan in the Earth Mistake World in this life, Reiger equally took note of this enmity and would definitely return it in full later.

Now, with the Basoros calculating without hesitation and having set him up with a bag of Gold Coins, how could Reiger not repay them in kind?

Therefore, once he learned of Yuri's plan, he didn't think twice and immediately took on the task of adding fuel to the fire.

"Let's begin."

Reiger closed his eyes.

Among the eleven types of magic he possessed, there were three that could cause Tactical Level destruction: Area Annihilation Magic.

One type was learned from Rephia, and it was a flame attribute Area Annihilation Magic—Simultaneous Fire Spear.

The other two were learned from the strongest Magic Guide of Ola, Revelia Leos Alfr.

As a member of the royal Elf family, known as 'magic's magical race', Revelia had a magical characteristic called 'Chant Connection'.

This magical characteristic allowed the Elf royalty to segment and connect the incantations of three of her magics, thereby producing different effects and power levels.

Through flexible use of Chant Connection, Revelia could break down each of her magics into three stages, multiplying her three kinds of magic by these stages and creating a total of nine different magic abilities to use.

It was for this reason that Revelia was praised by the gods and given the title of the Nine Demon Princesses.

The magic awakened by the Nine Demon Princesses only had three types, with the effects of attack, defense, and recovery.

But under the characteristic of Chant Connection, these three magics were divided into nine stages, turning into three types of attack magic, three types of defense magic, and three types of recovery magic.

Reiger had learned five types of magic from the Nine Demon Princesses, with four types he had not acquired.

Among these four types, three were the segmented Recovery Magic, which Revelia decided not to teach because she acknowledged that her Recovery Magic was no match for the Battlefield Saintess, Diya Flatel.

The remaining one was an Attack Magic that was also split into three stages; its power and effects were the strongest at the third stage.

She chose not to teach this particular magic solely because its power was too immense. Revelia dared not use it carelessly even in the underground city, fearing it might harm allies, damage the terrain, resulting in her own side's misfortune, and in the city, its use would be nothing short of a disaster.

However, Revelia did teach the first phase attack magic and second phase attack magic along with the other three defense magics to Reiger.

Now, the magic Reiger was about to use was this second phase attack magic, the most powerful among the three kinds of area annihilation magic he mastered.

"Before long, the flames will be unleashed."

The solemn incantation began to resound from Reiger's lips.

"[The quietly approaching flames of war, the inevitable destruction, the high-pitched sounding of the horns signaling the beginning of battle, all are enshrouded in the brutally chaotic warfare.]"

A magic circle, red like blazing flames, appeared beneath Reiger's feet.

"[Come forth, Red Lotus Flames, the merciless, fierce fire.]"

The magic circle began to expand, spreading across the entire rooftop.

"[Thou art the incarnation of Karmic Fire, sweeping away thousands of troops, bringing a grand-scale war to its conclusion.]"

The air temperature started to climb, filling the surroundings with scorching heat.

"[Burn everything to ashes, Sword of Surtur—My name is Alf.]"

Reiger slowly opened his eyes and transformed a vast amount of spiritual power into magic power, releasing it freely.

"[High-level Victory Sword.]"

The flaming red magic circle expanded rapidly at this moment.

The next second, flames appeared.

They surged from the magic circle as if Red Lotus Fire was erupting from the depths of hell, instantly turning the entire space crimson.

The temperature in the atmosphere rose swiftly to a degree that ordinary people could hardly endure.

The high heat rampaged, filling the entire tactical barrier to the brim, leaving no gaps.

Then, the ground ignited, the courtyard ignited, plants and flowers ignited, even the solitary mansion spared from damage mercilessly caught flame, entirely consumed by fire.

The Red Lotus Karma Fire, capable of burning everything to ashes, rampaged through the entire Freyja Clan, enveloping everything in flames.

This was a sea of fire that could burn all things within several kilometers to nothingness.

Reiger, standing on the rooftop of the gradually burning mansion, watched all this, his face and eyes seeming ablaze, being lit red as fire.

After a while, Reiger turned around, leaped with his body, and jumped off the mansion.

All that remained was this expanse of sea of fire, burning continuously there, as if it would never be extinguished.

...

Just as a massive magic array appeared in the sky above the mansion, and flames descended from heaven, covering the entire Freyja Clan, Yuri, who had withdrawn to the edge of the barrier, was in a daze.

"He actually used Tactical Level Magic..."

Gazing at the sea of fire emitting astonishing heat, Yuri felt somewhat astonished at this moment.

By her side, Marilyn was also looking at this scene with flickering eyes.

"Miss," Marilyn spoke in a low voice, "There seems to be a big secret hidden within Mr. Reiger."

Yuri pursed her lips and said nothing more.

Hiding a big secret?

Wasn't that obvious?

A man who had been lying in bed healing, getting up from it only to easily defeat a Shadow Knight of Swordsman level and to cast Tactical Level Magic, excelling in both swordsmanship and magic to such extents, was simply incredible.

The former Reiger Brillhaut definitely did not possess such abilities.

If he had, he wouldn't have been at death's door, almost getting killed.

But why had this man completely changed after being gravely injured?

It wasn't just his strength, even his personality seemed to have altered.

"...Do we need to investigate again? Miss?"

Marilyn's words were measured, and Yuri clearly understood what she meant.

She was suspecting that Reiger had ulterior motives.

Reason also told Yuri that she should do so, to find out if Reiger was intentionally hiding something, harboring some unknown scheme.

But—

"I don't want to doubt a friend," Yuri dropped these words and turned around, saying, "Have Ai En and Ian arrange everything, and then join us on the outskirts of the royal capital."

After speaking, Yuri left.

Marilyn stood still, her gaze following Yuri's departing figure, still flickering.

She knew Yuri was avoiding it.

Someone who could become a Marquis at 17 was naturally not a fool; Yuri was actually quite decisive, which was evident from her planning the counter against the Basoro Family.

But she had lived too constrained a life in the past, too suppressed, and now that she had finally found a friend she could confide in, she was unwilling to use that noble paranoia on them.

It was a rare friendship, her only friend, and the Miss really did not want to lose it, even subconsciously rejecting anything that might cause her to lose that person.

For that, Yuri could do everything for that person and could ignore everything for that person.

But oh...

"What matters most to us is you, not Reiger Brillhaut."

Marilyn gazed toward the fire behind her, a cold light flashing in her eyes.

Then, Marilyn also left.
